We all know about the chess game. Chess game is played on 8x8 board. Now, Alice and Bob come to play chess. They go to the chess grandmaster Magnus Carlsen to request him to organize their chess matches. So Magnus Carlsen organizes the match between them. But he sets up the new rules of the chess for the both players.
There are only two types of pieces: Knight and Bishop.
Each player is provided exactly one chess piece, either Bishop or Knight. (Both player can have same pieces.).
- Alice is the first player and Bob is the second player. They move their pieces alternatively.
- If anyone of them can capture the piece of the opposite player, then s/he will be the winner of the match.
- Both of them will play optimally.
You have to determine the winner of the match. If no one can win, then the game will be drawn.
Those who are not familiar with chess knights, note that in a single move, a chess knight can attack at most 8 positions within the board. A Bishop can move and attack diagonally at any position within the board as it is shown in the pictures below.
